如何使用 auth0 和 node.js 在服务器中获取 user.email？

Question

On my frontend, I can see the email through:

  console.log(auth.profile.email)

Then I call this service to retrieve some information from the backend, it's protected so you need to be logged in to get anything back:

var metadata_req = {
        method: "GET",
        url: "http://localhost:80/protected/all/metadata"
    }

On the backend, I'm using node.js and this to verify that the user is logged in before doing a request:

var jwtCheck = express-jwt({
    secret: new Buffer(config.secret, 'base64'),
    audience: config.client_id
});

But if I print out req.user, I only see iss, sub, aud, exp and iat. I would like to see the email as well.

Answer 1

You can get profile information in req.user by including the email permission when your user initially logs in.

For example, using lock in angular would look like this:

auth.signin({
    authParams: {
      scope: 'openid email'
    }
  }, function(profile, token) {
    // stuff
  }, function(err) {
    // error handling
  });

Change your API definition from "all/metadata" to "all/metadata/:emailId"

Call your API

var metadata_req = {
        method: "GET",
        url: "http://localhost:80/protected/all/metadata/{your_email_id}"
    }

In NodeJS retrieve you email_id from req.params.emailId
